To make the space-station, I drew a hexagonal polygon, used a 360 degree lathe on it. Then, I joined two cylinders in the middle, and did a boolean subtraction from the outer ring, so that they'd look like they were leading from the center into the rings. I painted them with a class/metal ring texture that I got from a lot of fiddling with sliders. The sphere in the centre uses one of the textures I created when doing the ships on the previous page.
